GAS-BURNER SUPPORT.

SPECIFICATION forming part of Letters Patent No. 783,181, dated February 21, 1905.

Application filed January 16, 1904:.

' To (LZZ whom it may concern:

which the following is a full, clear, and concise specification.

The object of the present invention is to provide a simple durable construction whereby the burners of gas-ranges, and more particularly the oven-burners of the same, may be readily removed for cleaning, &c., and whereby also their operating and controlling mechanisms may be conveniently interchanged from one side of the range to the other topermit of the range being installed in any position in a room, with the gas controlling valves and pilot-light located in the most convenient and accessible position with respect to the range.

In prior gas-ranges of which I am aware the oven-burners have had their gas-supply cocks and pilot-light permanently located on one or the other side of the range, which requires frequently that the range be disassembled or exchanged for another when the desired and most convenient position in the room happens to be one in which a wall or other object obstructs access to the valves. These difliculties are entirely overcome by the present invention, according to which the brackets or plates, which may constitute the sole supporting means for the burners, are quickly interchangeable from one side to the other and the gas-supply valves, together with the pilot, thus moved from right to left, and vice versa, without disassembling the range or requiring a great amount of time or skill; and, furthermore, the embodiment of this invention is such that theburners themselves may be quickly removed from the range and replaced by unskilled persons by simply lifting one end and withdrawing the burner from the compartment.

Reference is made to the accompanying two sheets of drawings, which form a part of this specification, and in which- Figure 1 is a side elevation of one of the burner-supporting plates as viewed from the Serial No. 189,224.

interior of the burner-compartment, the side walls of said compartment beingshown broken away. Fig. 2 is a top plan view ofFig. 1. Fig. 3 is an end elevation of one of the burners proper. Fig. 1 is a top plan, partly in section, of the supporting-plate for the open ends of the burnerand the pilot. Fig. 5 is a detail, and Fig. 6 is a transverse sectional view, of a burner-compartment with the plates and burners in position.

The opposite side walls of the burner-compartment are provided with apertures or openings 1, preferably disposed opposite each other and of the same shape and size, and each aperture is preferably, though not necessarily, provided with a slot 2 at one end for receiving a lug 3, formed on each of the plates 8 and 18, Fig. 6, which are adapted to be secured as interchangeable covers to the openings. The burners 4are tubular perforated bodies having their closed ends reduced or formed with feathered projecting pins 5 and their other ends enlarged to form a bell-shaped gas-receiving end or mouth 6 with its rim 7 slightly turned inwardly, as shown, so that it will fit and be easily seated in an end socket in the plate 8. which is the one located upon the valve-controlling side of the range. The plate 8 is of a single piece or casting, as shown, and is provided at one end with an offset flange 9, having the projecting lug 3 formed upon it, so that when the flange is inserted behind the end of the opening 1 the lug will enter the slot 2, and thereby hold the plate rigidly clamped upon the outside of the compartment-wall, completely covering the opening. The other end of the plate is provided with a similar flange; but it is adapted to rest upon the outside of the wall and be clamped thereagainst by means of a single stove-bolt 10, as shown. It is obvious that by this form of construction the plate 8 may be quickly disconnected from one side wall and secured to the other by simply loosening the bolt 10 and unseating the flange and lug 3. The body portion of the plate 8 is provided with one or more depressions or sockets 11, of which there may be any desired number, opening horizontally and inwardly and forming end seats for holding the open bellmouths of the burners, as above described. The range is connected with the gas-main at a point 15 in the rear, and a pipe 16 leads from thence and is supported parallel to the plate 8,,v'vith a gas-cock projecting from it opposite each socket, the free ends or nozzles 17 of the cooks passing through suitable central openings in the sockets 11, so as to be capable of directing a jet of gas centrally into the burners 4. Each socket is also provided with a series of apertures 12 for admitting air to the burner, and a perforated cover-plate 12 is adjustably mounted upon the outside of the plate, whereby the amount of air admitted may be regulated in the usual manner. In the middle of the plate, or, if there are more than one socket, between each pair of sockets, there is formed a passage 13, preferably with an inwardly-projecting neck, as shown, for holding the pilot-light 14. The latter is of the usual construction, and its tube is passed through the aperture 13, where it is secured to one of the nozzles, as shown.

The open or gas-receiving end of the burner forms, in conjunction with the socket 11, a chamber in which gas from the inlet 17 and air from the passages 12 are mixed, and the rim 7 of the bell-mouth is formed to fit rather snugly in the socket, so as to exclude air from the chamber, except from the passages 12, where the supply may be regulated.

The closed ends of the burners are supported by a plate 18, Figs. 1 and 2, which is of the same size and marginal construction as the plate 8, so that it may be secured interchangeably in either of the apertures 1 of the side walls, as above described. The inner side of the plate is provided with a set of projecting lugs 19, forming a seat for a yoke-piece 20, permanently secured therein by means of the bolts shown. In the case of a construction involving only two burners the ends of this yoke-piece are provided with suitable sockets opening upwardly to receive'the pins 5, and the bottom of each socket or seat 21 is grooved or slotted to register with the feather 22 on the end pin 5, the purpose of the feather and groove being to insure that the perforations in the burner will be held in the proper position to direct the flames in the desired directions. Where several burners are supported by the plates, sockets may obviously be formed at intervals intermediate of its ends. The plates 8 and 18 being thus of identical marginal size and construction are capable of fitting with equal facility into either of the openings 1 in the side walls of the burnerchamber, and inasmuch as the burners are supported entirely by them it follows that the controlling mechanism may be disposed upon any side of the range upon which there is an aperture. A change from one side to the other involves simply a removal of the burners, which is accomplished by lifting the pins 5 from their seats-and withdrawing the bellmouths from the end sockets 11, disconnecting the supply-pipe 16, and Withdrawing the nozzles from the plate, whereupon both the plates may be unbolted and interchanged and the gas-supply cocks mounted on the other side. It will be observed that both plates 8 and 18 are secured to and removable from the outside of the range by manipulating a single bolt, thereby obviating the difficulties usually encountered in ordinary ranges where bolts and screws must be unfastened from the inside of an oven or a warming-closet. The pilot-light while easily separable from the plate 8 by loosening the screw 23 will be more conveniently left Within the plate 8 during the interchange.

While 1 have described and illustrated my invention as applicable to oven-burners, it is manifest that it is equally serviceable in other forms and kinds of burners, and I wish it to be understood that the mixing-chamber may be formed wholly within the end of the burner, if desired, and that the style andshape of the burners and plates may be varied in many respects without departing from the spirit and scope of my invention.

Having described my invention, what l' claim, and desire to secure by Letters Patent of the United States, is
